Abbreviated Whole-Body MRI as a Novel Imaging Modality for Pediatric Lymphoma Follow-Up: A Multicenter study

Motivation: Our study is motivated by the need to assess abbreviated whole-body MR for evaluating treatment response in pediatric patients with lymphoma. Goal(s): To evaluate the diagnostic efficacy and reproducibility of a novel abbreviated whole-body MRI (WB-MRI) for response assessment in pediatric patients with lymphoma. Approach: We conducted a multicenter prospective study included pediatric patients underwent both PET/CT and abbreviated WB-MRI at baseline and during follow-up. Results: The image quality of abbreviated WB-MRI was rated good or excellent, with high sensitivity and accuracy. Impact: Abbreviated WB-MRI has the advantage of being non-invasive and without radiation exposure, making it an alternative to PET/CT for response surveillance in pediatric patients.
